JAMES STANLEY OF HASTINGS, MICHIGAN, ASSIGNOR OF ONE- HALF TO THOMASS. BRIOE, OF SAME PLACE.

DEVICE FOR PURIFYING FEED-WATER.

. Application filed September To all whom it may concern:

Be it known that I, JAMES STANLEY CAL- KINS, a citizen of the United States, residing at Hastings, in the, county of Barry and State of Michigan, have invented certain new and useful Improvements in Devices forPurifying Feed-Water and I do declare the following to be a full, clear,an d exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,'and to the letters of reference marked thereon, which form a part of this specification.

My invention is a device for removingimpurities from thewater fed into steam-boilers; and it consists in certain novel features showing my device in position therein.

hereinafter described and'claimed.

I11 the accompanying drawings,which fully illustrate my invention, Figure 1 is an eleva-I tion of a steam-boilenpartly broken away, Fig. 2 is an enlarged perspective View of the device. Fig. 3 is a cross-section of the same. Fig. 4 is a plan view of one of the trays, and Fig. 5 is a sectional View of the receiver..

The boiler A may be of any preferred construction and forms no part of my invention. The feed-pipe B, which leads from the pump, passes through the side or top of the boiler and enters a receiver 0. The said receiver is a cylindrical vessel having a spout D leading laterally from its upper end. The lower end of the feed pipe is'secured centrally to the bottom of the receiver, and thereby supports the same. J ust' above the'bottom of the receiver thefeed-pipe is provided with a rose or series of outlets E, through which the Water is discharged intothe receiver. Resting upon the boiler-fines or suspended within the boiler above the flues is an open frame F, having one or more crossbars G, on which I rest a series of trays H, having longitudinal partitions I, the alternate partitions of each tray terminating a short distance from the opposite ends of the same, so as to present the open spaces J and provide a tortuous passage for the water through the tray. Each tray is further provided at one corner with a discharge-opening K, and thetrays are so ar ranged that the openingin each tray is diagonally opposite the opening'in the preceding tray. Below the bottom tray I secure SPECIFICATION forming part of Letters Patent No. 608,250, dated August 2, 1898. Y 3,1897. Serial No; 650,457. (lio modeL) within the frame a pan L, which receives the water from the lowermost tray and from which a blowoff pipe M leads outside the boiler, the

said pipe being'provided with a'valve N, as

clearly shown.

The operation of the device wil l,it is thought, be readily understood. The water entering through the feed-pipe fills the receiver and overflows therefrom intothe uppermost tray. After passing tortuously through the said tray it falls onto the second tray and passes over. the same in like manner as over the first tray. After passing over and through all the trays the water is collected in the sediment-pan and overflows from the same into the boiler. In its passage from the receiver to the sediment-pan the water is gradually heated, so that after overflowing onto the fiues it is quickly converted into steam. The sediment which usually collects in the bottom 7 of the boiler is deposited in the sediment-pan and may be readily removed through the blow-off pipe by opening the valve therein, when the steam in the boiler will at once force it out. Some sediment will also be deposited in the receiver, which can be easily cleaned, as will be readily understood.

The deviceis very simple in its construction, can be applied to any boiler, and can be easily repaired. r

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination with a steam-boiler, of an open frame supported therein above the lines, a series of trays supported inthe said frame one above another, each of said trays having a series of longitudinal partitions, a sedimentpan secured in the open frame below the lowermost tray, a blow-off pipe leading from the sediment-pan, a feed-pipe entering the boiler adjacent to one end of the frame, a receiver secured toand supported by the lower end of the feed-pipe and provided with a spout projecting over the uppermost tray,and a rose or discharge formed on the feed-pipe just above the lower end of the same.

In testimony whereof I aftix my signature in presence of two witnesses;

JAMES STANLEY CALKINS. Witnesses:
